Not that I believe the site will go away anytime soon, but just in case:

public static final String FOCUS_MODE_CONTINUOUS_VIDEO

Continuous auto focus mode intended for video recording. The camera continuously tries to focus. This is ideal for shooting video. Applications still can call takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback) in this mode but the subject may not be in focus. Auto focus starts when the parameter is set. Applications should not call autoFocus(AutoFocusCallback) in this mode. To stop continuous focus, applications should change the focus mode to other modes. Constant Value: "continuous-video"
